摘　　要：铝电池托盘的焊道在打磨过程中面临轨迹复杂、焊道高度不一致、空间受限以及产品型号多变等困难。为此,基于新能源汽车的需求,研究了电池托盘焊道铣削打磨机器人系统。考虑打磨空间的限制性、焊道高度的变化及产品型号的多样性等因素提出了一种包含专用电气控制系统、恒力打磨机构、打磨轨迹规划以及视觉引导纠偏系统的解决方案,并建立了相应的打磨系统模型。实际验证结果表明,使用该系统打磨后,工件表面粗糙度均小于Ra6.3μm,整个打磨表面的平整度保持在±0.3 mm以内,满足了检测标准的要求。同时,单套设备的打磨效率达到了人工的4倍,显著提升了生产效率,验证了所设计系统的有效性和正确性。The grinding process of the aluminum battery tray weld faces difficulties due to complex trajectories,inconsistent weld heights,limited space,and varying product models.Therefore,based on the needs of new energy vehicles,a robotic system for milling and grinding the welds of battery trays is studied.The limitations of grinding space,changes in weld height,and the diversity of product models are considered,and a solution is proposed that includes a dedicated electrical control system,constant force grinding mechanism,grinding trajectory planning,and a vision-guided correction system.Corresponding grinding system model is established.Practical verification demonstrated that the system can control the surface roughness of the workpiece to less than Ra 6.3μm after grinding,the flatness of the entire grinding surface is within±0.3 mm,meeting the inspection standards.At the same time,the grinding efficiency of a single system reaches four times that of manual grinding,significantly improving production efficiency,verifying the effectiveness and correctness of the designed system.
